Before You Blame Behaviour: 5 Tack Checks to Make First

When a horse becomes resistant under saddle, it is easy to assume the issue is training, attitude, or freshness. But before behaviour is labelled as naughtiness, it is always worth checking whether discomfort could be part of the picture. 

Small tack issues can create big reactions. A pinching headpiece, an unstable saddle, or a girth that rubs can all affect how a horse goes, often long before there are any obvious physical signs.

Here are five tack checks worth making before you blame behaviour.

1. Check whether the saddle is still sitting level 

A saddle does not have to be dramatically wrong to affect the way a horse moves.

Signs to look for

Reluctance to move forward, hollowing, tail swishing, uneven contact, drifting through the shoulder, or resistance in transitions.

Why it happens

If the saddle tips forward, rocks, or sits unevenly, it can create pressure in key areas of the back and restrict the horse’s movement. Horses often respond by shortening their stride, tightening through the topline, or avoiding certain movements.

How to fix it

Check the saddle from the side and behind before mounting. Look at overall balance, wither clearance, and whether the panels appear to make even contact. If the horse has changed shape or the saddle has started to shift, it is worth reassessing fit sooner rather than later.

2. Look at the girth area closely 

The girth area is one of the most common sources of hidden discomfort.

Signs to look for

Ears back when girthing, biting, moving away when being tacked up, sensitivity behind the elbow, or reluctance to go forward once mounted.

Why it happens

A girth that is the wrong shape, too stiff, or sitting in the wrong place can pinch, rub, or restrict movement. Even a horse that stands quietly may still be uncomfortable once work begins.

How to fix it

Check for heat, rubs, hair disturbance, or tension in the girth area after riding. Make sure the girth suits the horse’s shape and that the buckles sit comfortably above the elbow. Cleanliness also matters, as dried sweat can quickly add to irritation.

3. Check the bridle for pressure points 

Bridle discomfort is often overlooked because the horse may not show obvious rubs.

Signs to look for

Head tossing, opening the mouth, crossing the jaw, pulling against the contact, or resisting one rein more than the other.

Why it happens

A bridle that is too tight, uneven, or poorly shaped for the horse’s head can create pressure around the poll, cheeks, nose, and jaw. The horse may respond by avoiding the contact or becoming tense through the neck.

How to fix it

Check that the browband is not too tight, the headpiece is sitting comfortably behind the  ears, and the noseband is adjusted correctly. Make sure the bit is also sitting evenly and not creating pressure at the corners of the mouth.

4. Don’t ignore pad bulk or layering 

More padding does not always mean more comfort.

Signs to look for

The saddle feels perched, unstable, or tighter than usual. The horse may feel short in the back or less willing to stretch.

Why it happens

Extra layers can alter the balance of the saddle and reduce spinal clearance if used without purpose. Pads that bunch or trap heat can also create friction and pressure.

How to fix it

Keep the setup simple and use only what is needed. One good-quality, well-fitted pad is often better than several layers trying to solve different problems at once. If you are using shims, make sure they are there for a clear reason and not just as a guess.

5. Think about whether the horse has changed shape 

A horse that was comfortable a few months ago may not be comfortable now.

Signs to look for

A change in way of going, more resistance than usual, muscle development, weight loss, weight gain, or returning to work after time off.

Why it happens

Tack fit is not static. Seasonal changes, workload, age, and fitness can all alter how the horse carries the saddle and bridle setup.

How to fix it

Review tack fit regularly, especially after time off, changes in feeding, or increased work. Being proactive is usually far easier than trying to solve a behaviour issue that has developed over time.

When behaviour is communication

Not every reaction is caused by tack, but tack should always be one of the first things ruled out. Horses often show discomfort through resistance long before there are visible rubs, white hairs, or major performance issues.

Quick pre-ride check

Before you assume your horse is being difficult, ask:

  • Is the saddle sitting level and stable?
  • Is the girth clean, comfortable, and correctly positioned?
  • Is the bridle fitted without pressure points?
  • Are the pads sitting flat and not too bulky?
  • Has my horse changed shape recently?

A few simple checks can prevent a lot of frustration. In many cases, improving comfort improves behaviour too.
